http://savannah.gnu.org/bugs/?33724 raised the issue that findutils is updating directory atime as part of traversing a hierarchy (and, according to POSIX, this behavior is the correct default). However, it would be nice to support the use of fts in a mode where O_NOATIME is used, so that directories don't appear to have an atime change merely because fts called readdir.
It looks to me like the only way to do this is to use open(O_NOATIME) followed by fdopendir() - but we are already using this approach for other reasons. So would it be worth a patch that adds a new FTS_NOATIME flag, and when that flag is set, pass in the O_NOATIME flag to all directories opened by fts? -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
